From what my guy told me, if the shoe is scuffed, and that's for any reason, then the peel is gonna happen. His had an abrasion and when he rubbed it they peeled.
So if you don't scuff then you are fine. If a scuff happens then you are not since the chrome isn't thick nor multilayered.
At least we're taking baby steps towards some kind of reality. Prior to this post... the lemmings were all talking about spontaneous peeling due to a manufacturing defect. Now we know there's no defect... and that you have to scrape them for any kind of issue to start.
